Coat of arms
Alhough the lordship of Baarsdorp and Sinoutskerke have been formally united in the fifteenth century, only Baarsdorp historically has coat of arms. These arms are also adopted by the combined lordship of Baarsdorp and Sinoutskerke.
The coat of arms of the lordship of Baarsdorp is described as " in sable a fess of silver, over everything a saltire of gules".
The coat of arms originally belonged to the noble van Baersdorp family, a branch of the Borssele family. The coat of arms of the van Borssele family can also be retraced in van Baersdorp's coat of arms. After the lineage of van Baersdorp was extinct, the weapon remained in use as the arms of the lordship of Baarsdorp.
Coat of arms of a lordship are not a a family coat of arms. In the past it sometimes occurred that a family coat of arms later became the arms of a lordship, as in the case of Baarsdorp. In the Netherlands, it is customary that owners of lordships add a heart containing the arms of the lordship to their coat of arms. In the event of the loss or sale of a lordship, such a shield is to be removed again.
